Connecting Wiring to the Field Wiring Arm
You make connections to the module through the 1771-WN field wiring arm. The arm pivots
on the I/O chassis to connect with terminals on the front of the module and acts as a
terminal strip. The wiring arm allows the module to be removed from the chassis without
disconnecting wiring.
1. Be sure all power is removed from the module before making wiring connections.
2. Swing the wiring arm up into position on the front of the module, noting that the
locking tab on the module secures it into place.
3. Make your connections to the field wiring arm as shown in the connection diagram,
using the label on the front of the wiring arm to identify your wiring.
WARNING
The optional 1771-WHF and 1771-WHFB fused field-wiring arms are not certified for use
in hazardous location applications. Use these optional accessories only in nonhazardous
applications.
WARNING
If you connect or disconnect wiring while the field-side power is on, an electrical arc
can occur. This could cause an explosion in hazardous location installations. Be sure
that power is removed or the area is nonhazardous before proceeding.
ATTENTION
Remove power from the 1771 I/O chassis backplane and field wiring arm before
removing or installing an I/O module.
• Failure to remove power from the backplane or wiring arm could cause module
damage, degradation of performance, or injury.
• Failure to remove power from the backplane could cause injury or equipment damage
due to possible unexpected operation.
IMPORTANT
The field-wiring arm terminal identification number is not the same as the number of the
bit that controls that output.
